The model demonstrates that beneficial feedback mechanisms can emerge in this “toy world” containing only self-interested organisms rather than through classic group selection mechanisms.

How plants changed Earth’s history. An hhipotesis is how the activity of photosynthetic hipotesks during Precambrian times have completely modified the Earth atmosphere to turn it aerobic, and as such supporting evolution of life in particular eukaryotic life.

She wrote that the composition of the Earth’s atmosphere, hydrosphere, and lithosphere are regulated around “set points” as in homeostasisbut those set points change with time.

Life, Temperature, and the Earth: All the atmospheric gases other than noble gases present in the atmosphere are either made by organisms or processed by them. Mechanical metaphors, according to Abram, lead us to overlook the active or agential quality of living entities, while the organismic metaphorics of the Gaia hypothesis accentuate the active agency of both the biota and the biosphere as a whole.

Gaia hypothesis

Lovelock has stated that this could bring an extremely accelerated global warming[19] but he has since stated the effects will likely occur more slowly. The hypothesis was formulated by the chemist James Lovelock [1] and co-developed by the hipotedis Lynn Margulis in the s. Staley has similarly proposed ” According to the data gathered by the Pic du Midi observatoryplanets like Mars or Venus had atmospheres in chemical equilibrium.

The resulting co-evolving dynamical process eventually leads to the convergence of equilibrium and optimal conditions”. Chapter 5 3rd Edition. When CO 2 levels rise in the atmosphere the temperature increases and plants grow. Retrieved 19 October Advances in the Astronautical Sciences.


During the “philosophical foundations” session hkpotesis the conference, David Abram spoke on the influence of metaphor in science, and of the Gaia hypothesis as offering a new jipotesis potentially game-changing metaphorics, while James Kirchner criticised the Gaia hypothesis for its imprecision.

Chelsea Green Publishing,p. The Earth is about to catch a morbid fever16 January Processing of the greenhouse gas CO 2explained below, plays a critical role in the maintenance of the Earth temperature hipoteis the limits of habitability.

Hipotesis GAIA by Laura Flechas Mejia on Prezi

In his defense of Gaia, David Abram argues that Gould overlooked the fact that “mechanism”, itself, is a metaphor — albeit an exceedingly common and often unrecognized metaphor — one which leads us to consider natural and living systems as though they were machines organized and built from outside rather than as autopoietic or self-organizing phenomena.

The Ages of Gaia: In a recent book-length evaluation of the Gaia hypothesis considering modern evidence from across the various relevant disciplines the author, Toby Tyrrell, concluded that: James Lovelock gave this name to his hypothesis after a suggestion from the novelist William Goldingwho was living in the same village as Lovelock at the time BowerchalkeWiltshireUK.

Later, other relationships such as sea creatures producing sulfur and iodine in approximately the same quantities as required by land creatures emerged and helped bolster the hypothesis. A New Look At Evolution. Schneider, Stephen Henry This growth brings higher consumption of CO 2 by the plants, who process it into the hiptoesis, removing it from the atmosphere.

The major questions were: The hypothesis contends that this system as a whole, called Gaia, seeks a physical and chemical environment optimal for contemporary life. From Wikipedia, the free encyclopedia.

Calcium carbonate is used by living organisms to manufacture carbonaceous tests and shells. Kirchner claimed that Lovelock and Margulis had not presented one Gaia hypothesis, but four. In contrast, on Daisyworld competition between the daisies based on temperature-effects on growth rates leads to a shifting balance of daisy populations that tends to favour a planetary temperature close to yaia optimum for daisy growth.

Another influence for the Hipotfsis hypothesis and the environmental movement in general came as a side effect of the Space Race between the Soviet Union and the United States of America. Most accusations of teleologism ceased, following this conference.

Potential effects and issues. The Gaia hypothesis was an influence on the deep ecology movement.

Gaia hypothesis – Wikipedia

It would appear that the claim that Gaia acts “intentionally” was a metaphoric statement in his popular initial book and was not meant to be taken literally. The Gaia hypothesis posits that the Earth is a self-regulating complex system involving the biospherethe atmospherethe hydrospheres and the pedospheretightly coupled as an evolving system.

Archived from the original on 9 February Link Lovelock, James The elements that comprise salinity do not readily change and are a conservative property of seawater. Views Read Edit View history. This hipotesi not the work of an individual but a collective of Russian scientific research that was combined into this peer reviewed publication.

Gai glacial lakes Desalination Drought tolerance Irrigation investment Rainwater storage Sustainable development Weather modification. Many scientists in particular also criticised the approach taken in his popular book Gaia, a New Look at Life on Earth for being teleological —a belief that things are purposeful and aimed towards a goal.

James Lovelock and Andrew Watson developed the mathematical model Daisyworldin which temperature regulation arises from a simple ecosystem consisting of two species whose activity varies in response to the planet’s environment.
